CHARLES E. KATSCH, OF NEW HAVEN, CONNECTICUT.

TIME CIRCUIT-CLOSER.

SPECIFICATION forming part of Letters Patent N 0. 659,480, dated October 9, 1900.

Application filed June 2, 1899. Serial No. 719,097. \No models To all whom it may concern.-

Be it known that I, CHARLES E. KATSOH, of the city and county of New Haven, in the State of Connecticut, have invented a new and useful Improvement in Clock-Controlled Apparatus, fully set forth and described in the following specification, taken in connection with the drawings, which form a part thereof,'

and in which Figure l is a View of clock, showing my device embodied therein; Fig. 2, a side elevation showing my invention; Fig. 3, a front elevation showing checking mechanism; Fig. l, a detail rear view of the operating device, and Fig. 5 a plan view of switch.

In all figures similar letters of reference represent like parts.

This invention relates to clock-controlled apparatus for the opening and closing of an electric circuit at any period of a day, and has for its object the construction of a mechanism which when in connection with a clock will be operated thereby to at certain periods open and close an electric switch for the purpose of furnishing or shutting ofi the current whereby light or power is furnished.

As set forth in the specification and drawings,tl1e device is used for incandescent lights, but may be applied to any use where an electric current is used without departing from the spirit of my invention.

In the drawings, A represents a casing containing the ordinary clock mechanism, the dial A of which is provided with a circular perforation d, in which a supplemental dial B, more fully described hereinafter, is adapted to revolve.

AgearB,havingseventy-two teeth,to which is rigidly secured a twenty-four-hour dial B, divided into a day and night dial of twelve hours each, is adapted to fit within the circular perforation d of the dial A and mesh with a gear A rigidly secured to the hourhand-carrying arbor Ct of the clock, so that said wheel B and dial B will revolve once upon every two revolutions of said gear A and hour-hand around the dial A.

Ratchet-wheels C and C, to the arbors of which are rigidly secured hands or pointers c and c, are adapted to fit within the dial-carrying wheel B and revolve with said wheel 13 and dial B, said Wheel C being journaled on one of the supports of a clock-frame D in well-known manner to hold gear B in a posi tion to mesh with gear A The wheels C and C are adapted to rotate upon the movement by the operator of the pointers c and c in the opposite direction from that in which gear B and dial B rotate and are held against rotation in the reverse direction by means of pawls c and 0 as shown in Fig. &.

On the wheel C is a laterally-extending lug c and on the wheel C is a cam 0 said lug c and cam 0 being so adjusted in relation to the pointers c and c that upon the revolution of gear 13 and dial B they will come in 0011- tact with and operate a pivoted lever D, secured to one of the supports of the clockframe D, to set a motor mechanism in motion at any desired time, as more fully described hereinafter. Lever I) consists of the arms d, d, and d said arm (1 having pivoted thereto a short arm d and d having pivoted thereto a longer arm 67;, which are adapted to rest when in their natural position on lateral extending lugs d and (Z secured to arms (1 and 01 as shown in Fig. a. 4

Secured within the casing A of the clock in well-known manner is a switch E, the contact e of which is mounted on an axle E, said axle also having rigidly secured thereto a gear 6 and wheel a on the periphery of which are notches Figs. 1, 3, and 4. Gear e is adapted to mesh with a gear f, forming a part of a motor mechanism F, secured within a skeleton support F in said casing A and consisting of gears f, f, and f, on the gear f being a cam F, with an abrupt shoulder f while the gearfis connected with a spring f and I gear f with a fly-wheel f This mechanism constantly tends to rotate the axle l, on

which is mounted the contact 6, but is checked from so doing by means of checking mechanthat in its normal position the outer end of rod g rests in notch e of wheel 6 and the outer end of rod g against the shoulderf on the cam f ofgearf, as shown in Figs. 1 and 3.

A rod II is attached to the arm d of lever D and extends through an opening in the casing of the clock, so that said arm cl may be drawn downward thereby and the rods g and g of the checking mechanism released from the notch e of wheel 6 and shoulder f of cam f respectively, to operate motor mechanism F independent of its operation by the mechanism of the clock proper.

A pivoted shoe I is attached to the skeleton support F, and to the outer end of said shoe I is attached a red I, extending through a perforation in the casing of the clock, so that the inner end of said shoe I may be forced in or out of connection with the flywheel) of motor mechanism F to stop the operation of said wheel and motor mechanism when the same would otherwise be in operation, being released from contact with the checking mechanism.

Wires K are attached to the switch E in well-known manner and extend through a perforation in the clock-casing to the incandescent lamps or burners. Not shown.

As assembled, the gear B is adapted to mesh with the gear A at the point denoted by the figure 12 on the day portion of dial B, at which time the clock is supposed to be started.

In operation the pointersc and c, which are marked or otherwise distinguished as the lightingand extinguishing pointers, are set by the operatoropposite the-hours on dial B at which it is desired that the lights are to be lighted and extinguished. As the dial B revolves with the movement of the hour-hand of the clock by means of gears B and A the pointers 'c and c and wheels 0 and C also revolve until first pointer c on dial B reaches the point in line with figure l2 on the clockdial A, when lug 0 will come in contact with the outer end of arm 61 and raise the same in well-known manner, so that arm (1 of lever D will be forced downward, which draws rod G downward, causing rod g to also be drawn downward, thus partially rotating shaft g, thereby withdrawing said rod g out of engagement with notch e on wheel 6 and rod g out of engagement with shoulder f on cam f thereby setting in operation motor mechanism F, which meshes with gear 6 and thus revolving contact 6 a sufficient distance to make the connection and close the circuit. Lug sliding over the end of arm d, as dial B revolves allows lever D to assume its normal position, when rod g will be forced back into the next succeeding notch e on wheel 6 and rod g against shoulder f in cam to check motor mechanism F. As pointer c on dial B reaches the point in line with figure l2 on the clock-dial A the cam 0 comes in contact with the outerend of arm (l (over which thelug c is adapted to pass without contact) and the motor mechanism F again put in operation, as stated above, to withdraw the contact 6 and extinguish the lights.

When the operator desires to aii'ix the pointers c and c at a point past the arms (1 and cl of lever D, lug 0 as it passes the upper edge of arm 01 will swing said arm on its pivot sufficiently to pass it, when said arm will drop back into its normal posi tion on lug d cam c causing arm d to operate in a similar manner.

Having now described my invention, what I claim, and desire to secure by Letters Patent, is-- In a clock-controlled apparatus, the combination with the mechanism of a clock; of a gear adapted to mesh with a gear secured to the hour-hand arbor of said clock mechanism; a dial secured to said first-mentioned gear; ratchet-wheels adapted to fit adjacent said firstanentioned gear and rotate therewith; arbors secured to said ratchet-wheels; pointers secured to said arbors adapted to rotate said wheels in the opposite direction from that in which the dial rotates; pawls adapted to engage said wheels and hold them against reverse rotation; a switch; motor mechanism adapted to operate said switch; laterally-extending lugs on said wheels, and a lever adapted to be tripped upon the rotation of said dial and wheels, to operate said motor mechanism, substantially as described.

In witness whereof I have hereunto set my hand,at New Haven, in the county of New Haven, State of Connecticut, this 22d day of May, 1899.

CHARLES E. KATSCII.
